3 or 4 small spines.
Hab. Trawling-ground, Plymouth, common; Moray Frith, Scotland.
This species unites G. Andrewsii with G. nexa, and, I think, has often
been mistaken for the young of the latter; but G. nexa, so far as my
experience goes, is a species peculiar to the north of England, whereas
G. dispersa, I anticipate, will be found to be the most universally
dispersed, in deep water, of any of the species known. It can always be
detected from G. nexa by the form of the hand and the manner in which
the fingers impinge: in G. nexa the hand is broad towards the extremity,
and the fingers meet only at the apex; in G. dispersa the hand gradually
narrows to the apex, and the fingers meet each other through their
whole length, the inner margin of the finger being finely serrated, the
thumb not.
It also may be distinguished from G. Andrewsii by the breadth of the
hands, which are narrow and round in G. Andrewsii, and moderately
broad and flat in G. dispersa.
By an examination of the texture of the integument under a magnifying
power of low degree, the surface of G. dispersa will be seen distinctly
to differ from that of any of the others; it is covered with flat scales,
fringed with short cilia. The length of the animal, including the arms, is
about 2-1/4 inches.

Catalogue of Hymenopterous Insects collected at Celebes by Mr. A. R.
WALLACE. By FREDERICK SMITH, Esq., Assistant in the
Zoological Department, British Museum. Communicated by W. W.
SAUNDERS, Esq., F.R.S., F.L.S.

This collection of the Hymenoptera of Celebes is specially interesting,
as adding greatly to our knowledge of the geographical range of many
well-known species, while the additions made to the Fossorial group
contain many of great beauty and rarity. A new species belonging to the
tribe of Solitary Wasps, Odynerus clavicornis, is perhaps the most
interesting insect in the collection; this Wasp has clavate antennæ, the
flagellum being broadly dilated towards the apex, convex above and
concave beneath. I am not acquainted with any other insect belonging
to the Vespidious group which exhibits such an anomaly.
Fam. ANDRENIDÆ, Leach.
